5.1.2 Explanation of simple mode parameters
Refer to the separately available Instruction Manual (detailed) for details.
z You can select whether write to various parameters can be performed or not. Use this function to prevent
parameter values from being rewritten by misoperation.
Pr. 77 "parameter write disable selection"
Setting Description
0 Parameter write can be performed. (Write is enabled only during a stop in the PU operation mode.)
1
Parameter write cannot be performed. (Write to Pr. 22, Pr. 75, Pr. 77 and Pr. 79 "operation mode selection"
is enabled.)
2 Write during operation is enabled.
REMARKS
• Parameters below are write-enabled during operation even when Pr. 77 = "0".

z You can clamp the upper and lower limits of the output
speed.
Pr. 1 "maximum speed", Pr. 2 "minimum speed"
CAUTION
Note that when you have set the minimum
speed, merely turning on the start signal will
start the motor at the preset speed, without the
input of the speed command, according to the
acceleration time setting.

Speed
z You can select any speed (RH, RM, RL) by simply
switching the external contact signal.
z You can also set each speed to any value within the
range of 0 to 3600r/min during inverter operation.
z Using the extended function, you can set up to 15
speeds.
Refer to the Instruction Manual (detailed) for the
setting method.
Pr. 4 "multi-speed setting (high speed)"
Pr. 5 "multi-speed setting (middle speed)"
Pr. 6 "multi-speed setting (low speed)"

High speed ON OFF OFF
Middle speed OFF ON OFF
Low speed OFF OFF ON
z The time taken to reach the Pr. 20 acceleration/
deceleration reference speed (factory-set to 1500r/
min) from 0r/min is set as the acceleration time, and
the time taken to reach 0r/min from the Pr. 20 (factory-
set to 1500r/min) speed is set as the deceleration
time.

REMARKS
z Increasing the value reduces the sound level
but increases noise and leakage currents.
z Set or "1" in Pr. 240 "Soft-PWM control" to decrease
motor noises.
Refer to page 66 for Pr. 240 "Soft-PWM control".
